SPECIFIGATION'forming part of Letters Patent No. 516,173, dated March 6,1894.

Application filed February is. 1893. smart. 462,035. at as.)

To all whom it may concern:

Be it known that I, J OHAN F. BJURLUND, a SHbJGGt of the King'of Swedenand Norway, and a resident of New York city, in the county and State ofNew York, have invented certain newand nsefulImprovements inSash-Springs, of which the following is a specification.

My invention consists of an elliptic spring whereof the two members are'oifset laterally or in diiferent planes relatively to each other sothat one may be inserted between the sash stile and the stop, while theother is seated on the stile outside of the stop and is fastenedthereto, so as to form a simple, efficient and reliable spring that maybe readily ap-J plied to any window for preventing rattling V and forholding the sash when raised, it desired, all as hereinafter fullydescribed refer ence being made to the accompanying drawmgs in which-Figure 1, is a front elevation of part of a window with my improved sashspring applied, part of the sash stop being broken out. Flg. 2, is avertical section through the glass pane and side view of the sash stileand stop with my improved spring in the position of use. Fig.3, is aside view of the spring alone.

I take a thin fiat metallic plate of spring metal, and make a slit a,along the middle portion nearly its whole length separating said platefor the most part into two members I), 0, but leaving intact connectionsof suitable length at (Land to one of said members -c, I provide alateral foot plate 6, for attaching to the stile f, of the sash, saidfoot plate being like the rest of the plate of which the spring iscomposed out out of a blank plate of suitable width, and having one ormore screw holes g for the fastening screws; and having thns preparedthe plate I stamp, press OF NEW YORK, N. Y.

or otherwise set the two members apart in the. elliptic form as shown inFig. 3, and then apply the spring with the member 1), between the faceof the sash stile f, and the sashstop h, as shown in Figs. 1 and 2 andfasten the spring on the front of the sash stile, as shown best in Fig.1, thus making. a very simple spring that may be applied without makingany recesses or holes in the wood of. either part andwithout any fittingwhatever except fastening the foot' plate with one or more screws, andit may also be applied where the sla 1; space between the face of thesash stile is o more than the thickness of the plate of which the springis made, the spring being 55 eoinpressedmo the flat condition.

The spring may be cut out from the blank plate, slitted, punched for thescrew holes, and the two members shaped and set all at one operation ofa suitable pair of stamping I pying different planes side by side andset in elliptical shape, whereby the spring may be '70 applied with onlyone 0t its members between the sash and the sash stop substantially asdescribed.
